Tenable, a software company, agreed to acquire Alsid, which provides information security services, for $98m. "Tightly controlling the privileges of accounts in Active Directory is as foundational to reducing risk to the business as the basic blocking and tackling of deploying security updates. As we've seen with the flurry of hacks, ranging from the sophisticated SolarWinds compromise all the way down to common ransomware attacks, attackers go after the Active Directory infrastructure to increase access and establish persistence. We’re impressed with the insights that Alsid brings to enterprise customers and look forward to working with the Alsid team to add this critical element to Cyber Exposure and risk management," Amit Yoran, Tenable Chairman and CEO.
